#5 32-40 Barrel

Print Post  
I have a 32-40 barrel that is a #5 size, it was 28 inches and it was just too heavy for 200 yard standing, so I cut off 4 inches. Still shot very good, but still too heavy for me. I'm 70 and have lost some strength from being behind a desk for 20 years. So now what can I do to lighten this baby up?

I was told that sometimes fluting a barrel can screw up the accuracy of a barrel. Whether this is true or not I don't know.

So what can I do, I have a 3 inch forarm that I was planning on shaving the sides to about 2 inches and then chop off about 3/8 inches off the bottom to ride a little bit lower in the front rest, which shouldn't loose much weight, so where can I loose some heft.
This is a cpa rifle.

thanks Cry

Barrels may be of any length in excess of 21 ˝ inches and any weight but for benchrest rifles the barrels shall be about 2 inches in diameter or less, and not less than the above designated length of 21 ˝ inches from the rear of the breech face to the end of the muzzle. The barrel need not be rifled for the entire length but must fully encircle the bullet as it passes through the unrifled section. Sights may be mounted on an extended rib but the barrel must meet the above minimum length restriction.


That is the rule for barrel length Van. You can cut it shorter. You can also turn it down in the lathe. It can be fluted too.

I would shorten before I would flute.   Less chance of putting something into the barrel that would not help performance.  No telling how the gunsmith is going to flute some good some not.

Sometimes cutting shorter has a negative effect, Anything choke bored it's going to hurt. Friend of mine cut down a Anschutz position rifle barrel to make a silhouette gun out of it. Those have a muzzle swell and are well known good shooters due to the slight choke to the muzzle.  It went sour after the cut.

That # 5 is a Douglas I believe and should be the same size whole way so cutting down to 22 inches should not hurt at all. Short and heavy is a good thing for offhand rifles.  Plus the easiest thing to do is cut shorter. No re-bluing re-setting sights or scope blocks

If it's not an original barrel why don't you just have it turned down or replaned to a smaller diameter? It is not that difficult.

I agree with 1/4 bore. #5 barrels are ridiculous. I once owned a Hi High Wall Schoyen with a #5 barrel. I happily traded it for a takedown Hi Wall schuetzen with a #3 30/40 barrel.

Joe, what in the heck are you talking about

Barrels may be of any length in excess of 21 ˝ inches and any weight but for benchrest rifles the barrels shall be about 2 inches in diameter or less, and not less than the above designated length of 21 ˝ inches from the rear of the breech face to the end of the muzzle.

Joe, so you're saying that in ISSA matches I can't have a barrel less than 21 1/2 inches?
Didn't know that.

That rule, I copied from the ASSRA rules Van. I didnt look at ISSA rules or WSU rules.  

ISSA barrel length rule is the same as ATF regulation.  

You could try a .22 Crackshot for OH Van. Nice and light. Ooops! Here we go again. Legal in ISSA but not legal in ASSRA.   

Have you tried a rifle rest while shooting OH Van?  That way you only hold the rifle up for a few seconds per shot.

ASSRA rules were changed at the Annual Meeting in 2010 to a barrel length of 16" . They are posted as a word document at (You need to Login or Register to view media files and links)



Section 1.16   Barrels
Barrels may be of any length that conforms with federal law and any weight but for benchrest rifles the barrels shall be no more than 2 inches in diameter or  2 inches as measured across the flats of an octagon barrel. The barrel need not be rifled for the entire length but must fully encircle the bullet as it passes through the unrifled section. Sights may be mounted on an extended rib but the barrel must meet the above minimum length restriction. A bloop tube may be added to extend the length of sight radius, but adjustable barrel tuners are forbidden. 

Cheers,
Laurie

Thanks Laurie.

This is the problem with posting the rules on the internet. 
A new paper hand book of rules needs to be printed. 

How in the SH is a schutzenmeister supposed to use the rules when they have been posted on the net and then changed and not updated in the rules link?  A new book in the pocket, on the line!

Dont get me started!   Angry

Joe,
The changes to the Match Equipment and Scoring Rules were adopted at the Meeting in May. They were published in the September/October Single Shot Journal. So all members have the corrections in hand. I am not sure why the original link to the rules was not changed and didn't notice it till I went looking for it this afternoon. I will be contacting Josh to get the link to the old rules removed.
Cheers,
Laurie

That issue of the journal is in a box above the rafters in my shop. 

My old rule book is in my shooting box.  I'll take two new updated rulebooks.  Thank you.

As a schuetzenmeister, I went to the Internet and ran off a set of the rules in their current configuration.  I even ran off a fancy Orange card stock cover for it.  Now nobody can argue about the rules at CSV!!

PS  Shouldn't this part of the thread be moved to its own topic under "General?"

You know America is really going down the drain when Schutzenmeisters have to print their own unofficial rule books from unreliable links.

I want an * official * rule book from the ASSRA just like we've always had in the past. I dont want Greenfrogs rule book. I'll pay for them. I want two. 
When we are armed with THE official rule book, there is no question. It's right there in the book, at the range, on the line. 

No offense meant toward you Frogster. 

Yes, this thread has gone way off course. It's all Vans fault.
